- Abstract
The current economic development in China is largely replied on the huge consumption of fossil fuels, resulting in emission of the vast amount of air pollutants. Under this circumstance, it is of vital importance to explore the relationships among economy, energy and air pollutants so that the targeted policies and suggestions for each province will be proposed. Based on the emergy and decoupling index methods, this study calculated the GDP, energy consumptions and air pollutants in 30 provinces from the year 2015 to 2017. And then five indicators were established which included the ratio of fossil energy to non-fossil energy (RFN), energy use per unit GDP (EUPG), environmental cost per unit GDP (ECPG), impact of emissions per unit energy consumption (IEPEC), and economic-energy-air emission decoupling index (DI). The result demonstrates that the consumption of renewable energy in eastern and northeastern parts of China are obviously largely than the other provinces, while the energy efficiency of Beijing, Tianjin and southern parts are higher than other regions. The indicators ECPG and IEPEC are largest in the western and some under-development central regions, but the emergy loss in 30 provinces shows a declining trend year by year, especially the dust emission. In terms of decoupling index (DI), the indicator DIemission-GDP of Liaoning and Inner Mongolia are respectively 2.36 and 4.58, grouped into recessive decoupling status due to the economic depression. While the left 28 provinces are in the status of strong decoupling. The indicators of DIenergy-GDP are intricate, while most of provinces are in the status of strong decoupling. In general, the relationship among economy, energy and air pollutants shows a sustainable development trend. In the future, some targeted development patterns for different provinces should be proposed for 30 provinces.
